Tube Amp Archive

yeah, I'm cool. And I thankyou for your concerns!!!!
I gotchya now. thanks. will report back..

edit... Thanks for the guidence. She sounds great, pure jcm grind.

The grid stoppers on the output tubes look legit. 5K6? Try changing the 120K to 220K and you'll reduce the negative bias voltage to the point where you can adjust it for EL34s. The grid return resistors also look like they're set for 6550s (or maybe KT66s). With EL34s, Marshall would have used 220K...

yeah, you can see that it has been changed, and the added ones on each power tube socket....

JCM 800 20th anny. had KT66's. one blew. I am trying to rebias with a set of el34's, using a bias right, I can only get the bias up to 10.2 mv with the marshall bias pot full clockwise. I notice added resisters in line at power tube sockets, and possibly a changed one as well in front of the bias po...

nevermind, I found info, Thanks.

Thanks guys for the explanations in layman's terms.
Mucho Thanks!

Hey guys, please explain to me the "what does it do for the amp"... V1, and V2, and V3 so i can better understand my amps a little more. I do not want to assume anymore and wish to be informed. Amps in question, my marshall 2204 and my concorde. what I know, or at least i think I assume as V1 is the...

This one will have the switching/footswitch system for the Fast/Gradual switch that Komet should have built it with. That switch is useless in a gig recording situation since you have to reach around a hot amp on a dark stage and switch it during a song?????? :roll: This will have a SS switch with ...

Hey guys.... I'm a guitar luthier, Tech, Player.... I can fix a guitar, but ignorant on my amps... needs some basics... Could I swap different power tubes in my concorde? KT66's? ect.? out of all the new el34's out there, I like the svet winged c's the best, but wouldn't mind trying something else ...

I like both. kinda like 2 amps in one at a flick of a switch.

Ive had my Komet Concorde now for about a year. Ive had many amps in my life. No other amp sounds as good. I even hate to gig with it and look for substitute,..... another Komet would suffice... Seriously though, It be hard press to seperate me with my Concorde. Pure magic. And I do play hard, loud,...

has anyone attempt to clone the Twinmaster?
would love to have.
